I am subscribed to this thread because at one time I was looking to add both an ipod interface and a handsfree cel phone system to my 2004 330CiC. I have yet to do either, but if I could pull the trigger on the handsfree cel phone set up, I'd almost certainly do this as well. Does anyone in this thread have or know the best system for our cars? Does this system for the ipod also work in conjunction with a system for handsfree phone use?
